To all whom t may concern: y

' Be it known that I, JOSEPH V. GRoLLn, a citizen of the United States, residing at Sunnyvale, in the county of'Santa Clara and State of California, have invented certain new and useful Improvements in Combined Back-Rests and Tables, of which the following is a specification.

jMy invention relates to new and useful improvements in a combined back rest and l table.

The principal object of the invention is the construction of a device of this charac`-l ter which is adjustable tovarious angles.

Anotherobject is the construction in such a manner that all parts may be collapsed so that they may be stored in a small space or carried from place to place.

VA still further object is the provision of a table which is detachable from the back rest.

With these and other objects in view my inventionconsists of the novel details of construction and arrangement of parts as will be more clearlyunderstood from the following specification and. drawings in which:

Figure 1 is a side elevation..

Fig. 2 is a top plan.

Fig. 3 is a front elevation.

Fig. 4 is a detail perspective of one end of the detachable table.

Fig. 5 is a detail perspective of the end of the table supporting arm, and

- Fig. 6 is a transverse section on the line 6-6 of Fig. 3.

In the drawings the numeral 1 indicates a base frame having upstanding lugs 2 formed on each corner of the rear end and lugs 3 formed on each corner of the forward end. Bars 4 are pivotally connected to the lugs 2 at 5 and are provided on the front edge with a plurality of spaced notches 6 which are of the shape shown and for the purpose as will be presently described. A knob 7 is secured on the outei1 face of each of the bars 4 at the top end thereof whereby the bars may be grasped for swinging upon the pivot.

Angle bars 8 are pivotally connected to the forward lugs 3 by means of a pin 9 and are provided in their sides with elongated openings 10 the purpose of which will be presently described. In cross section the angle bars 8 are, of the shape illustrated in i Fig.. 6 of the drawings and. at the upper ends are provided with a flange 11. The upper edge of the angle bars is bifurcated and a and the flange 11. The cross pins or rods 12 are adapted to be received in the notches 6 of the bars 4 as is more particularly illus trated in Figs. l and 3 of the drawings. T he bars 8 are connected at the top end by means of the cross bars 13 and if desired the bars 4 riight also be connected by a cross bar or ro A plurality of buttons or knobs 14 are secured to the frontedges of the bars 8 and are adapted Vto pass through eyes or open'- ings in the fabric 15 which is stretched across between the bars 8 as is more particularly illustrated by dotted lines in Fig. 2 of the drawings. The buttons or knobs 14 may 'be of any desired type and thefabric may be of any desired material.

Bars 16 are pivotally connected to the lower end of the bars 8 by means of the pin 9 and the bars 16 are provided on their outer faces with a threaded stud 17 which is adapted to pass through an elongated opening 18 formed in an arm 19. A thumb nut 20 is received on the threaded stud 17 and engages the outer face of the arm as is more particularly illustrated in Figs. 1 and 2 of the drawings. The rear end of the arm overlies the bars 8 and a bolt 21 passes through the elongated opening 10 and through the end of the arm to receive a thumb nut 22 whereby the end of the arm is connected to the bar.

The forward end of the arms is provided with an extension indicated at 23 and a hook member 24 is formed on the extension, in the position, shown, for the purpose as will be presently described.

My detachable table is indicated at 25 and has an upstanding flange 26 formed on the rear edge thereof. The flange 26 terminates a distance from each end of the table 25 and spaced lugs 27 are formed adjacent each end of the table on the rear edge, and have a pin 28 extending transversely thereof. The pin 28 is adapted to be received beneath the hook member 24 and the table will rest upon the extensions 23 of the arms.

From the above detailed description it will be found that I have provided a combined back rest and table which is adjustable to various angles and which may be collapsed to be convenienti-y from place to The table 25 may be used as a ,book Arest or for holding other articles for eating or other Purposes- The .back rest ,may be adjusted to various angles by merely .raising the bars fl, through means Aoff the knobs 7 and the pins A1.2 maybe adjusted into various notches 6. `Of course it will be understood that the lbars 1 6 are also adjustable with relation to the arm -19 by releasing the thumb screw 17 and adjusting the threadedstuds in the elonated openings 18. The arm 19 may be adjustedavith vrespect to the bars 8 by releasing the thumb nut 22 so that the threaded bolt may be adjusted in the elongated opening 10'- The table 25 may V-be easily7 'detached from `the arm 5 by slightly raising the -forward end so thatthe pins 28 may be Withdrawn from beneath Athe hook member 24. When the tableis to be replaced lthe pins are engaged beneath the hook 2a and when lowered the table ,will -rest Kupon the extension 23 as previously described.

It Will he understood thattwo bars il are used, and that I also use ytWo of the bars 8, tivo l,ofthe bars 1G, and tufo arms 1 9 -to make up the completed structure. The various parts of my invention are preferably .cons `s tructed of some metal such as aluminum `expedient in the scope of the appended claims.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is l. In combination with aback rest, arms secured to the back rest, `extensions formed on the arms, hooks formed on the arms adjacent the extensions, yand a table received on the v eX-tensions, said table having pins secured to and spaced from one edge adapted to engage beneath the hooks on the arms.

2. In combination with a back rest having arms connected thereto, hooks formed on the top of the arms, and a table, lsaid table provided with spaced lugs, and a pin supported between the lugs and adapted to L engage the hooks on the arms.

In testimony whereof I affix my signature in presence of two Witnesses.
